ls -al ~/.ssh

Generate a new SSH key

Paste the text below, replacing the email used in the example with your GitHub email address.

ssh-keygen -t ed25519 -C "This email address is being protected from spambots. You need JavaScript enabled to view it."

The key is saved into the file id_ed25519

start the ssh-agent in the background

eval "$(ssh-agent -s)"

to automatically load the keys into ssh-agent

open ~/.ssh/config

Type in this

Host github.com AddKeysToAgent yes UseKeychain yes IdentityFile ~/.ssh/id_ed25519

Add your SSH private key to the ssh-agent and store your passphrase in the keychain. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_ed25519 in the command with the name of your private key file.

ssh-add --apple-use-keychain ~/.ssh/id_ed25519
